London Will Start Powering Public Buses With Coffee Grounds

London authorities have chose to translate some of the buses on biofuel made from waste coffee and "diesel".

"Our Coffee Logs have already become the fuel of choice for households looking for a high-performance, sustainable way to heat their homes - and now, with the support of Shell, bio-bean and Argent Energy have created thousands of litres of coffee-derived B20 biodiesel which will help power London buses for the first time", he said. The firm believes it would take just over 2.55 million cups of coffee to create the enough biofuel to run a London bus for a year once the oil has been blended with diesel.

Coffee grounds are now being used to produce biofuel for London buses, it has been confirmed.

The B20 biofuel contains a 20 per cent bio-component which contains part coffee oil.

Bio-Bean's biofuel is then directly put into selected London buses, which if continued, can decrease emissions from the transport industry through innovations in second-generation biofuels.

Despite their traditional penchant for tea, Londoners drink an average of 2.3 cups of coffee a day, producing about 200,000 tons of used grounds, the news release said. The switch also helps towards Britain's clean growth strategy. Founder Arthur Kaytells the Independent that coffee actually has very high oil content - 20 percent by weight - so "it's a really great thing to make biodiesel out of". Given London mayor Sadiq Khan's recent declaration that all new single-decker buses in London will run on zero-emission fuels starting next year, coffee-powered B20 looks to be a suitable complement to the electronic buses the city plans to purchase in the months and years ahead. Will the streets of London now smell of fresh coffee?

Redskins RB Chris Thompson Carted Off With Knee Injury
Prior to the Redskins' Week 11 game, Thompson was their best offensive player on the field, showing off his dual-threat ability. The drive that followed was capped by a 40-yard Cousins TD pass to Ryan Grant , who was all alone behind the coverage.
